SPECIFICATION forming part of Letters Patent No. 686,596, dated November 12, 1901.

Application filed May 5, 1900. Serial No. 15,668. (No model.)

To all whom it may concern.-

Be it known that I, ROGER DAMONTE, a citizen of the United States, residing at New Orleans, parish of Orleans, State of Louisiana, have invented an Improved Steam-Generator, of which the following is a specification.

The invention is an improvement in that class of steam boilers or generators in which water circulates from a stand-pipe through one or more pipe coils or convolutions. The novel feature is the provision of a rotary valve for controlling escape of steam from the several pipe-coils, whereby the latter. may be conveniently cleaned whenever required.

The details of construction, arrangement, and operation of parts are as hereinafter described, reference being had to the accompanying drawings, in which- Figure 1 is a vertical section of a steamgenerator including my invention. Fig. 2 is an enlarged cross-section on line 2 2 of Fig. 1.

A vertical stand-pipe A is arranged concentrically within a casing B, which also in.- closes grates C, and a series of pipes D, coiled spirally about the stand-pipe A, and connected therewith at their upper and lower ends, the latter being all in the same horizontal plane. The rotary valve E is arranged in the stand-pipe A, so as to connect the steam-outlet pipe F with any one of the coils D that may require to be cleaned. The said valve E is practically in the nature of an open-ended tube, having a horizontal and vertical portion and rotating within the circular space provided between the open ends or mouths of the several coils D. The exit-pipe F passes down and out beneath the grate-bars O, as shown. The valve E is rotated and adjusted at will by means of bevel-gearing G and a horizontal rod H, that extends out through the stand-pipe and casing B, its outer end being provided with a hand-wheel I for rotating it. The said rod is arranged in a tube or pipe J, which extends between the stand-pipe and easing, as shown. It will be seen that one of the meshing bevel-gears is fixed vertically on the rod H and the other horizontally on. the valve E. The latter rotates upon the pipe F as a center and is adapted to be brought into coincidence with any one of the pipe-coils as shown. It is adjusted with a coil on the left, and hence steam is allowed to escape or blow off from the coil through the valve and'pipe F, whereby the coil is cleaned. By rotating the valve E by means of the rod H and gearing G it may be adjusted successively in coincidence with all the coils D for blowing 0E and cleaning the same as required. It will be understood that the valve E may be adjusted with its mouth or upper end between the mouths of the pipe-coils D. and that in such case passage of steam or water through it and the pipe F is cut off, since the valve-mouth then forms a steamtig'ht joint with the circular and concentric valve-seat with which the coils connect.

The coils D rest upon transverse supports K. These may be pipes connecting with vertical pipes L and M, arranged exterior to the casing B. The pipe L is in practice the water-supply for the stand-pipe A, with which it communicates through the connectingpipe K.

A blow-01f N for the stand-pipe is arranged in the lower portion of the same.

It will be seen that the upward course of the products of combustion from the grate O is a spiral one, the same passing beneath and also above each of the several coils D from one end to the other. Thus heat is utilized and economized to a high degree and steam rapidly generated.

It will be seen that the several pipes D are so arranged as tolie in close contact, so that the passage of products of combustion upward between them is practically prevented and the same pass in immediate contact with the pipes, whereby a maximum heat efiect is produced. By this arrangement the invention is distinguished from others, in which a series of horizontal pipe coils or convolutions are arranged spirally around a stand-pipe, but spaced apart, and with which a spiral plate is employed for guiding and directing the products of combustion spirally around the stand-pipe.

What I claim is 1. In a steam-generator of the class described, the combination, with a stand-pipe and one or more pipe-coils connected therewith, of a hollow valve, which is adapted to rotate in the plane of the mouths of said coils,

and an exit, or blow-off, pipe, connected with the said valve, substantially as shown and described.

2. In a steam-generator of the class described, the combination with a stand-pipe and a series of pipe-coils connected thereto, of a hollow rotary valve arrangedin said stand-pipe and adapted to communicate with any one of said coils, means [or rotating said valve, and a pipe connecting therewith, substantially as shown and described, whereby any one of the coils may be out out of the circulatory system and allowedto blow off as specified.

3. In a steam-generator of the class described, the combination with a stand-pipe and a series of spiral pipe-coils connected thereto, of a blow-0E pipe and a hollow rotary valve adapted to communicate with any ROGER DAMONTE.
